摘要：

以现代低压电力线载波技术为背景,围绕油井的井下与地面通信进行研究。采用扩频通信以解决电力线噪声干扰,并针对重频干扰,设计改进了耦合电路,尤其是耦合器前端滤波器,消除了噪声。具体实现时,采用SSCP485扩频通信芯片,结合SSCP111放大芯片和PIC18单片机,搭建了油井通信的发射接收系统,实现了高速准确的数据通信。实验证明,扩频通信对电力线噪声具有良好的对抗能力,同时,验证了本系统在数据发送、接收、处理等方面的可靠性与稳定性。

Abstract:

Based on the modern technology of low voltage power line carrier,we make a fundamental study of the communication between the land surface part and the underground part of the oil well.We solve the problem of power line noise interference through spread spectrum communications and improve the coupling circuit,especially the filter in the front part of the coupler,in view of cycling frequency interference.Specially,we construct the trans-receiving system for the oil well with the SSCP485 chip (spread spectrum carrier),the SSSCP111 and PIC18 MCU.The experiment shows that the system is reliable and stable in the aspects of data transmission,receiving and processing.

Key words: power line carrier;spread spectrum carrier communication;oil well;power line couple tech SSCP485
